Microscopy and Surface Roughness at End-Milling of OL37 Steel
Journal Title: RECENT - Year 2011, Vol 12, Issue 33
Abstract
In this paper a study, based on a factorial experiment, microscopy and surface roughness results in milling steel cylinder front-OL37 is presented. Variable parameters in the experiment were: cutting speed, feed rate and depth of cut. The levels of these variables and the experimental program are presented. The kinematics of cutting for milling operation has been studied, demonstrating that is a rolling motion with gliding, the blade point trajectories are modified orthocycloides. Surface roughness results on two perpendicular directions: longitudinal and transverse has been measured. Modern equipment used allowed values for Ra, Rz, Rq on both directions. Values factorial experiment results were tabulated, and after processing nonlinear relationships were obtained for the parameter Ra. Microscopic images and diagrams of the surface roughness are presented. Also, relationships for roughness have been established.
